The present invention relates to a toothpick with an interdental brush functional structure, characterized by comprising a long rod, a semi-open type long sleeve member and a spring sleeve member. The long rod has a holding section and a tooth-picking section extending from one end of the holding section. The tooth-picking section has a thin and soft fork-like shape, and the holding section is provided with a device that rebounds the tooth-picking section automatically, so that the tooth-picking section can be fast shifted back and forth in the semi-open type long sleeve to allow the thin and soft fork-like portion to protrude out of the tubing and swing on the tongue-side of the teeth, thereby enabling the toothpick to insert into the teeth slit to completely hook out food residue and scrape tartars between the teeth as well as behind the teeth to achieve effective cleaning of teeth.一種具有牙間刷功能結構之牙籤，其特徵包括：一長桿、一半開放式長套件及一彈簧套件，其長桿具有一握持段及從握持段一端延伸形成的一剔牙段，其剔牙段呈細扁柔軟叉子狀，而握持段設有使剔牙段自動彈回之裝置，可使剔牙段在半開放式長套件內快速前後移動，細扁柔軟叉子狀突出管道時透過牙縫，可在牙齒的舌面擺動，藉此伸入齒縫中以完全勾出食物殘渣並刮除牙間和牙齒後面的牙垢，以達到牙齒有效清潔。
